Abstract
The present invention relates to the field of building material, in particular the process for making and use of permeable steel slag colored pavement bricks, characterized in that steel slag is used as coarse and fine aggregate to replace sand and gravel, wherein the raw materials of the colored pavement bricks are added with 60%-80% of steel slag with grain size being 0-20mm apart from the No. 425 common silicate cement. In the forming process of the steel slag colored pavement bricks, the die roof board is provided with 5-15 inverted polygons or cones, thus forming a series of inverted taper holes on the opposite sides of the pavement bricks during vibration molding.
Description
Technical field
The invention belongs to building material field, particularly a kind of slag color paving tile with pervious function.
Background technology
The pavior brick that occurs roughly divides ceramic base and cement based road surface permeable brick at present, but because the permeable brick cost in ceramic base road surface is too high, can't promote on a large scale at present.The permeable brick in cement based road surface can't overcome the excessive problem of strength degradation after the freeze thawing at present fully.Slag is a kind of metallurgical solid waste of present more difficult high value added utilization, all has the more serious problem of storing up in each big steel mill of China.Storing up of big steel slag takies a large amount of soils on the one hand, and wasteful buret is managed expense and caused certain environmental pollution.
Summary of the invention
The objective of the invention is to give full play to the characteristics that slag has certain hydraulically active, prepare high performance permeable pavement brick.
A kind of slag color paving tile with pervious function, adopt the identical forming method of colored bright the paving brick of at present full ripe waterproof type, it is characterized in that replacing sand, stone as thick, fine aggregate with slag, can bring into play the hydraulically active of slag, having added the 60%-80% granularity in the color paving tile raw material except that No. 42.5 ordinary Portland cements is the slag of 0～20mm, and promptly ash/sand is than being 0.20-0.40.
For increasing the water-permeable of pavior brick, at the top board of mould 5-15 inverted cone (polygon or circle) is installed and formed a series of back taper holes at its back side when making paving brick in vibratory compaction in the colored paving brick moulding process of slag, the tip of cone penetrates bright of colour and goes up the hole that the chase of spill decorative pattern partly forms porous.The decorative pattern chase also has the function of charge for remittance and water guide except having decoration and antiskid function.The structure of the permeable brick of slag colored road surface as shown in Figure 1.The pattern of its front and back as shown in Figures 2 and 3.
Slag color paving tile production technique is
When producing purple, redness, black, mazarine, dark colour permeable pavement brick such as blackish green,, make colored cement earlier a small amount of No. 42.5 ordinary Portland cements and pigment mixing.The preparation of colored cement accounts for 1～5wt.% by pigment, and cement accounts for the ratio of 95～99wt.% to be mixed.The a small amount of colored cement of the 5～10wt.% that accounts for the total consumption of cement that mixes is first at the mold bottom uniform distribution, ash/the sand that will mix then than be 0.20～0.40, water/gray scale be 0.45～0.55 slag sand---cement admixture is poured mould into, and on shaking table, carry out vibratory compaction.Time of vibration is 3～5 minutes.When producing the colorful water-permeable brick of white, yellow, light green, pink, light blue or other pastel shade, should adopt white portland cement during formulating colorful cement No. 42.5.
The maintenance under wet environment and the room temperature condition more than 10 ℃ of base substrate band mould after the moulding can be carried out the demoulding after 1～3 day.Base substrate after the demoulding also needs to place under wet environment and the room temperature condition more than 10 ℃ more than 27 days, can be used as finished product and sell after check.
The permeable brick of this slag colored road surface basic unit when making should adopt slag sand or natural sandstone to handle.Should mix and stir the lime of 5～10wt.% when adopting natural sand, the hydraulically active owing to himself when adopting slag stone can not add lime.Slag sand or the natural sand that is mixed with lime are laid 5～20cm, and carry out re-laying the slag color paving tile after the compacting.The effect of firm permeable brick is not only played by the basic unit of laying with slag sand or natural sand, also plays the effect of water holding layer.After rainwater oozes under by permeable brick, because slag sand or the bigger porosity of natural layer of sand can be deposited and be received a large amount of rainwater and then slowly be penetrated into the soil deep.Therefore after finishing by the such scheme construction, surface gathered water can be do not made yet, more rainwash can be do not formed even run into 60mm/ hour heavy rain.Produce the permeable brick ingredient requirement of slag colored road surface:
(1) cement: for meeting commercially available No. 42.5 ordinary Portland cements of national standard.
(2) slag: be the slag of converter, open hearth, electric furnace or the steel-making of other method.As adopting the slag of new generation, its process of cooling should have the water spray process of cooling.As make air-cooled slag, should display 1～2 year.Slag need be crushed to the granularity of 0～20mm.
(3) be used to make colored bright cement and should be white cement No. 42.5, brightening agent and pigment use same brightening agent and the pigment of producing general color paving tile.
Compare with ceramic water-permeable brick, the present invention can reduce the production cost of colorful water-permeable brick significantly, need not calcine simultaneously, but save energy, the protection environment.Compare with the permeable brick of present existing cement based, avoided the shortcoming of freeze-thaw resistance difference, make colored bright easily, help the beautifying city.Distinctive reverse taper hole structure design of product of the present invention and rollet water gathering system not only make this product that good water-permeable is arranged, and can also guarantee that permeable hole is not stopped up by dust, make the good pervious function of the long-term maintenance in road surface.
